Seminoe Reservoir is a 20,300-acre hidden gem located in south-central Wyoming, offering exceptional fishing opportunities amid spectacular scenery. Formed by the Seminoe Dam on the North Platte River, this picturesque reservoir features 180 miles of rocky shoreline and a water capacity of 1,017,279 acre feet. With a maximum depth of 206 feet and mean depth of 50 feet, Seminoe provides diverse fishing environments throughout its 24-mile length. The reservoir has two major sections: the main North Platte River arm and the 12-mile Medicine Bow River arm. Home to trophy-sized fish, including past state record walleye, this reservoir delivers memorable fishing experiences with fewer crowds than many other Wyoming fishing destinations.
